PLATE-MACHINE Specification of Letters Patent.

Patented June 15, 1909.

Application filed March 10, 1906. Serial No. 305,398.

or other purposes where thin sheets of metal are required, and in the common form of such. machine it is necessary that a man or catcher stand behind the rolls in position to receivethe plates as theyissue from the rolls, and after the plates are so received the catcher swings the ends thereof 11 ward on top of the-upper roll and shoves t e plates back to the rougher to re-i'oll the plates, this operation being continued until-the plates have been reduoedtothe desired thickness. After the plates have been reduced to the prescribed thickness they are withdrawn from the machine by thecatcher and disposed upon; a suitable off-bearing table.

Considerable skill is required on the part of the operative or catcher behind the rolls to properly manipulate the plates, and-such laor is comparatively expensive. The primary object of the present invention is'to produce an automatic mechanism of a comparatively simple and positive nature, and the operation of which may, at all times, be under the complete control of the rougher from a point where he ordinarily stands to introduce the sheets to the mill, and of such character that it will automatically receive the plates as they ass out from between the rolls, return said p ates over the top of the uppermost roll to a position where their ends may be caught by the rougher and again fed to the rolls, and to mechanically transfer a completed plate to a suitable offbearing table, chute or other support.

By the operation of the improved machine the necessity of manually catching the plates, or other manipulation of the latter behind the rolls, is entirely overcome. more, by the use of the im )roved; mechanism all the advantages derived from the removal of this particular work, from the uncertain care and limited capacity of human labor and putting it in charge of a reliable and surely acting machine are obtained, and in addition the cost of the production of the plates is materially cheapened.

In the drawings, Figure 1 is a top plan Fu rthere I View of the m achinc embodying the features of the invention. Fig. 2 is a side elevation of the same. Figs. 3 and 4 are longitudinal .vertical sections of the machine showing the parts in two positions, the plate receiving carriage in Fig. 3 being lowered to take the plate from the rolls, and in Fig. 4 elevated to return the plate rearwardly over the rolls. Fig. 5 is a detail perspective view illustrating guide and clutch operating means cooperating with the rear portions of the shouldersr Fig; 6 is a detail elevation particularly showing the controlling clutch mechanism. Fig. 7 also shows a detail elevation in planes at right angles to that illustrated by Fig. 601 the controlling clutcli mechanism, parts ;of the devices cooperating with the clutch mechanism being shown in section.

Similar numeralsof reference are employed to indicate corresponding parts in the several views. I v a The numeral 1 designates a roll frame, having therein a pair of rolls 2 and 3, arranged in vertical relation and having adjusting means 45 cooperating therewith. The rolls and their supporting frames, as well as the adjusting means, may beof any suitable type, and in the present instance are of the two high type.

The rolls andframe, as shown in the accompanying drawings, are illustrated merely to disclose a practical organization, and it is to be understood that any modifications known in the art may be adopted and used in place ofthe roll organization particularly illustrated T he entire machine will be held on a suitable base rest or support, and includes opposite pillars or uprights 5 and 6.

In rear'oi and close to the roll frame 1 is a power transmitting shaft 7, extending transversely with relation to the machine and adapted to receive power from a suitable engine or jack shaft. The shaft 7 is rotatably held in suitable journal boxes mounted on pillow blocks or uprights 8., and keyed thereon is a master gear 9. Shiftably mounted on the shaft 7 is a frictional elementoperating a sleeve 10, with spaced friction disks 11 and 12, and an outer grooved shifting head 13, which is engaged by one end of a shifting lever 14. The sleeve 10 of the friction element is suitably splined or other vis disposed and secured on one end of a counter shaft 16, extending along the one side of the machine and rotatably held in suitable hearings or uprights 1.7 The counter shaft 16 is controlled as to its reversal of rotation by engagement of the motion transmitting disk thereon with either disk 11 and 12, as will be readily understood. On the shaft 16, adjacent to the motion transmitting disk 15 is a groovedbelt wheel. 18, and on the rear extremity of such shaft 16 is a double grooved belt wheel 19.

In rear of the rolls 2 and 3, and in alinement with the contiguous portions of the faces thereof, are upper and lower guides 20 and 21, respectively having reversely inclined contiguous faces 22 and 23, which are s aced a sufficient distance to permit various thicknesses of plates to pass therebetween during the operation of reducing the thickness of the plates. One of these guides is shown by Fig. 5 in detail, both guides being -racticall equivalent in structure, and each as a she t 24 terminally disposed in vertical bearing slots 25 formed in rearwardly projecting extensions 26, the said shaft carrying uide rollers 27 which are fixed thereto. These rollers 27 are arranged on opposite sides of the transverse center of the shaft 24,

and the lower guide 21 differs from the upper uide 20 by having rear lugs or bosses 28, and %y which a clutch controller is mounted, and

1 consists of a forwardly dished plate 29, having trunnions 30 disposed in the lugs 28 and a downwardly depending central arm 31 The u per edge of the plate 29 stands high'enou h afiove the upper surface of the guide 21 to e in the path of movement of the plate passing between and rearwardly through the rolls 2 and 3. The upper portion of the plate 29 has such maximum normal projection above its sup orting guide that it will always be positive Y operated by the plate comin through or being fed rearwardly between t e rolls 2 and 3, and as the upper part of the plate is engaged and forced over rearwardly by the plate fed through the said rolls 2 and 3, the ower part of said plate 29 and the arm 31 will be swung forwardly or in a reverse direction.

The under edge 32 of the arm 31 is cut away to loosely contact with a stud 33 carried by the upper end of a throw-lever 34 fulcrumed at its lower end on the upper terminal of a post or analogous support 35, and having a pull-link 36 pivoted to the intermediate portion thereof and provided with a rear downwardly curved terminal 37 movably attached to a draw-latch 3S slidably passing through an upright or post 39, and also secured to an adjacent terminal 40 of a longitudinally slidable clutch yoke 41 extending downwardly under and codperating with a clutch sleeve 42 on a carriage actuating shaft 43. The clutchyoke 41 in its opposit-e terminal 44 carries a pin or projection similar to the end of the draw-latch 3S,

and has an enlarged shank 46, which is similar to the said latch and movable in a post 47, the posts 39 and 47 serving as guides or supports for the two latch bolts. The pinsor ends 38 and 45 of the latch bolts or slides alternately coeperate with the clutch sleeve 42, and the yoke 41 has a retractile spring 48 secured to the lower portion thereof and to the post 47 to cause the yoke 41 to always have a tendency to move rearwardly when the clutch controller held by the lower guide 21 is disengaged with respect to a plate passing rearwardly between the rolls 2 and 3. The clutch sleeve 42 is splined on the carriage controllin shaft 43 and is shifted longitudinally wit relation to said shaft against a spring 49 surroundin the shaft and operatin to throw the said clutch sleeve outwar 1y when released. The clutch sleeve 42 has an outer toothed face 50 in contiguity to a toothed hub'or rim 51 of a gear 52 running loose on the shaft 43, and always held in mesh with the master gear 9 on the ower tran'smittim shaft 7. The clutch eeve 42 is formed with agroove 53, which has a cam face 54 provided by a web extending across from one end to the other of the said sleeve, and terminating in a shoulder 55, as clearly illustrated by' Figs. 3 and 4.

On opposite ends of the carriage controlling shaft 43, cranks 55 are disposed and have reciprocating rods 56 secured thereto,-

the shaft 43 a locking block or arm 61 is secured to rotate with the shaft and are arranged close to the inner side of one of the cranks 55. The locking block or arm 61 has diagonally opposed rounded corners or heels 62 and 63 and an ular stop corners or faces 64 and 65. The unction of this look ing or stop arm or block 61 is to prevent the cranks 55 having motion in a downward direction in any one position, and which might otherwise ensue owing to their weight, and also to obviate any tendency to upward motion of said cranks when in a reverse position or during the time that the angular corner or stop face 64 is rearward or in the position that the stop face 65 occupies, as shown by Fig. 6. This locking or stop arm or block engages an upright check 66, pivotally held at its lower end in a socket 67, open at the rear and provided with a straight shoulder '4 1 art sans or wall 08 at the front. The upper end of the check is inclined dowmvardly and for- "wardly, as at 69, to facilitate movement of the curved heels 62 and 63 thereover. The check 66 is held in normal upright position by a spring 70 attached to the front edge thereof and also to a'portion of the base of the machine, as shown by Fig. 1.

The position of the cranks as illustrated by Fig. 6, will be effected when the carriage is lowered and forwardly projected, as illustrated by Fig. 3, and at a time when it is imperative that any accidental movement of the carriage be avoided hec'ause the plate from the rolls 2 and 3 is be ing fed on to the forward extremity of said. carriage, and any movement of the latter during such time would result seriously, not only from -a standpoint of breakage of the mechanism, butfrom an improper disposition of the plate.

Fixedly supported in rear of the rolls 2 and 3, and having its forward extremity practically in alinement with the upper portion of the roll 2, is a rack or transfer frame, consisting ofside bars 71, connected by cross bars 72 .and having roller shafts 73 and 74 journaled thereon, and each provided with pairs of sprocket wheels 75 and 76 traversed by longitudinally disposed chain belts 77. The rear ends'of the side bars 71 are secured to the up or end of depending bars 78, in turn attac ed at their lower ends to the front extremities of longitudinally disposed members 7 9 held on the uprights 5, the latter being preferably connected by a suitable cross tie-rod 80 to strengthen the same. The members 79 are each formed with a cam slot 81., havin a top opening 82, for convenience in assemb ing the parts, as will be presently explained. The cam slot 81 of each member comprises an upper front downwardly inclined straight face 83, merging into a similarly inclined face 84, having a greater angle, the latter face merging regularly into a lower horizontal face 85, from the rear terminal of which the slot takes an upward trend to form a nearly vertical edge 86," continuing into a pocket 87. From the pocket 87 the edge of the slot takes a downward trend to form an angular face 88, in aiinement with the face 83.

Rigidly held in about central relation to the slot 81 is a shoe 89, secured to a supplemental upright or support 90 also rigidly attached to the upright 5, as clearly shown by Fig. 2. The upper and lower edges of the shoe 89 are shaped longitudinally to correspond to the various portions of the slot 81 contiguous thereto, and to the rear upper portion of said shoe an upwardly projecting spring actuated switch tongue 91 .is movably attached, and is normally held in advance of the pocket 87. A downwardly projecting spring actuated switch tongue 92 is movably attached to the forward end of the shoe 89. The switch tongue 91 is freely movable in a rearward direction, and the switch tongue 92 in a forward direction, and said switch tongues control the movement of an engaging element in a manner which will be present'y explained.

The shaft 74 has, on opposite ends, grooved pulleys 93 and 95, the pulley 93 being traversed by a belt 95 also engaging the grooved pulley 19 of the counter shaft 16. The grooved pulley 94 is surrounded by a belt 90, which also engages a grooved pulley 97 on the one end of the shaft 24 of the upper guide 20. The shaft 24 of the lower guide also has a grooved pulley 98 thereon which is traversed by a belt 99 running to a grooved pulley 100, keyed on. the power receiving shaft 7. By means of the pulleys and belts just described, the sprocket chains 77 engaging the sprocket wheels 7 5 and 76 of the rack or frame supporting the same, will always be moved in the direction of the arrows, as shown by Figs. 3 and 4, or so that the plate delivered or transferred to said chain belts will be moved over the upper portion of the top rail 2 within convenient reaching distance of the rougher or feeder. The shafts 24 in the upper and lower guides 20 and 21 will also be moved in a proper rearward feeding direction, as indicated by the arrows shown by Figs. 3 and 4, and the shaft 24 of the upper guide will be free to move vertically owing to the slots 25 with which the ends thereof engage to com ensate for variations in thickness of the p ates passing between the guide rolls.

The carriage 60 is constructed as an open frame, and has a front reduced extremity .101, which is adapted to fit in the rear extremity of the return rack or frame in advance thereof and having the sprocket wheels 75 and 76 and chain belts 77 included as a part thereof. The frame 60 also has shafts 102, 103, 104 and 105 extending transversely thereacross, the shafts 102, 103 and 104 carrying two pairs of sprocket wheels, as at 100. The shaft 104 is a drive shaft for the remaining shafts 102, 103 and 105, and from the in nor sprocket wheels of the shaft 104 chain belts 107 run to and surround the inner sprocket wheels of the shaft 103, and from the outer sprocket wheels of the latter shaft chain belts 108 run to and surround the outer sprocket wheels on the shaft 102. From the outer sprocket wheels on shaft 104, chain belts 1.09 extend and traverse sprocket wheels 110 on the shaft 105. At the forward reduced end 101 of the carriage 60, stub shafts 111. project inwardly and carry sprocket wheels 112, one on each, the said sprocket wheels 112 being engaged by chain'belts 113 traversing the inner sprocket wheels on the shaft 102.

The uprights 6 each have a longitudinally extending head 114 thereon from which end bearing bosses 115 project outwardly to re ceive the terminals of a longitudinal carriage shifting shaft 116, on which are fixed opposing frictional cone disks 117, which are al ways held close to the bearing bosses 115. On the forward end of each shaft 116 is a grooved pulley 118, the pulleys 118 being respectively connected by bolts 119 and 120 with the forward grooved portion of the pulley 19 below, and another double grooved pulley 121 at the opposite side of the machine, and which is actuated by a transversely extending belt 122 from the rear grooved portion of the said pulley 19. Each head 114 is formed with a longitudinal slot .123, and projecting through and slidable in the slot 123 of the two heads are the opposite extremities of the shaft 104 held on the carriage 60. On the projectin ends of the shaft 104 are cone friction dis s or pulleys 124, which will be preferably covered by some yielding material, and are adapted to be thrown .into alternate engagement with the cone friction disks 117 to reverse the movement of the shafts 102, 103, 104, 105 and 111 and the sprocket wheels and chain belts cooperating therewith.

The carriage 60 is shiftable in reverse directions longitudinally of the machine, and

also has an elevating and depressing movement, all of which are carried on automatically through the medium of the reciprocating rods 56 and the operation of the carriage controlling shaft-43 and the clutch mechanism hereinbefore described. When the carriage 60 is depressed, as shown by Fig. 3, all of the chain belts, sprocket wheels and shafts on the said carriage, as just described, have motion imparted thereto in such direction as to cause said parts to rotate and move toward the rear of the carriage, and this direction of motion is effected by reason of the en agement of the frictional cone disks or pu leys 124 with the forward cone disks 117 on the shafts 116. When the carriage 60 is elevated it is moved rearwardly and the shaft 104is shifted in the slots 123 of the heads 114, and the cone disks or pulleys 124 are caused to contact with the rear cone disks 117 of the shafts 116, and consequently the shafts 102, 103, 104, 105 and 111,

together with the sprocket wheels and chain" belts cooperating therewith, are caused to rotate and move in a reverse direction, or toward the forward end of the machine. The carriage 60, at a proper point with respect to its length, has side studs 126 projecting outwardly therefrom and engaging the cam slots 81 in the members or blocks 79, and on the studs 125 are antifrictional rollers 126 mounted to ease the movement of the carriage with respect to the inner sides of the said members or blocks; ,flZV hcn the carriage 60 is in lowered position, the studs 125 are in close contact with the forward intersccting portion of the lower horizontal edge and the downwardly inclined edge 84 of the cam slot 81, and in advance of the switch tongue 92. The operation of the mechanism to elevate the carriage, as will be more fully hereinafter set forth, causes the studs 125 to ride up over the switch tongues 92 in close contact with the upper edges of the shoes 89 and force the switch tongues 91 real-wardly and pass into the pockets 87, clearing the upper ends of the said switch tongues 91. The switch ton ues 91 being liberated, resume their normal position, and clear what may be termed the rear passages of the cam slots 81 embodying the substantially vertical edges 86 and communicating with the lower horizontal portions of the cam slots including the edges 85. The carriage when empty is normally held elevatedfor a certain length of time, with the parts in the position shown particularly'by Figs. 2 and 4, and when the mechanism again automatically operates to lower the carriage to receive a plate the studs 125 pass downwardly behind the switch tongues 91 in close. contact with the edges 86, and eventually travel over the horizontal edges 85, forcing the lower projecting ends of the switch tongues 92 upwardly until the said studs 125 5 rest at the point of intersection of the edges 85 with the edges 84 in advance of the tongues 92 and in position for a further elevating motion, as just described.

In the description of the return rack or frame, heretofore set forth, and embodying side bars 71, it was stated that the said rack is held in fixed relation to the upper roll 2. This is true, and such fixed position will be maintained by the bolts and 96, but in i the event of repair being required at the rear of the machine, or close to the rolls 2 and 3, or for other purposes, the said rack or frame, after release of the belts 95 and 96, may be disposed to clear the rear portions of the rolls and roll frame, and to arrive at this result the bars 71 are pivotally connected to the upper ends of the bars 78. It will also be seen that the front extremities of the bars 71 are reduced to permit them to be 1brought into closer relation to the upper rol 2.

From the foregoing descri tion, the operation of the machine will, no iloubt, be understood, but to briefly summarize, the motion of the shaft imlparts through the master gear 9 meshing witi the 'gear 52 rotation to the shaft 43 when the clutch sleeve 42 has its toothed head 50 forced into engagement with the toothed rim 51 of the said gear 52, and which will be the normal positions of the parts just specified. The actuation of the shaft 43 causes the cranks 55 to make part of a revolution in one direction, the cranks returning through another path, or do not come back over the same path, but do make and during'sucli horizontal movement of the carriage the studs 125 will be moving over the a complete or full revolution and force the carriage or table, with the assistance of the connecting rods and rocker arms to make one complete trip, or to have a complete movement from normal position, or starting point, down through the slides, the carriage or table being forced through the lower switch by the first half of the revolution of the cranks 55, and brought back upwardly over the lower switch along the upper slide and through the upper switch back to the starting point. hen the cranks are completing the last half of their revolution and when the carriage or table is thus brought back to the starting point it will be in elevated position, as shown by Fig. 4. During this operation the locking block or member 61 is correspondingly overthrown to have opposite sides thereof brought into engagement with the upper end of the check 66.

When a plate or a bar is fed to and passes between the rolls 2 and 3, and engages the clutch controllerembodying the upwardly projecting late 29, carried by the lower feed guide 26, t e clutch sleeve 42 on the shaft 43 is disengaged from the gear 52, and the motion of the shaft 46 ceases, and in this condition the end or pin 38 'of the slide 38 is withdrawn-frommthe groove 53 of the clutch sleeve 42 and out of the way of influence by the cam face 54- through the medium of the interposed throw-lever 34, having the stud 33 and the pull-lever 36 connected to the drawlatch 38, and the pin or reduced end of the slide 46 is thrown into engagement with the clutch sleeve and bearsagainst the shoulder 55 ofthe latter. In this position, the carriage will have been lowered almost vertically and shifted forwardly so that the front extremity thereof will be under the platepassing rearwardly through the rolls, as illustrated by Fig. 3, the carriage remaining inthis lowered position until the plate shall have cleared the rolls 2 and 3 and the plate 29 of the clutch controller, when the spring 49 on the shaft 43, and which was compressed when the clutch sleeve 42 was thrown-out of engagement with relation to the'gear 52, will force the said clutch sleeve outwardly and establish connection thereof with the gear 52, and at the same time the pin or end 45 of the slide 46 will move rearwardly into disengaging position with relation to the clutch sleeve, and the pin or reduced end 38 of the slide 38 will be again brought into cooperative relation to the said clutch sleeve. The clutch sleeve 42 is also immediately rotated in the direction to draw the rods56 forwardly throughthe medium of the cranks 55 and shift the carriage in a rearward direct-ion in a substantially horizontal plane until the forward end of said carriage is in a position to clear the rear extremity of the rack or frame including the side bars 71,

cated by the arrows in Fig.

switch tongues 92 and upper edges of the shoes 89. The forward movements of the rods will continue until the studs 125 pass upwardly in close contact with the switch tongues 91, and in moving over the latter tongues the forward extremity of the carriage will continue to rise until said tongues are cleared and. the studs 125 pass into the pockets 87 of the members 79. At this time, the cranks 55 of the shaft 43 will have been fully overthrown toward the front of the machine, and the shoulder 55 of the clutch sleeve 42 will be bearing or resting on the end or pin 38 of the slide 38, and the said clutch sleeve will have been again disengaged and the carriage permitted to remain elevated until the plate received thereby from the rolls 2 and 3 shall have passed over and in engagement with the chain belts 77.

When the carriage is lowered, as shown by Fig. 3, the cone friction disks 124, on the shaft 104, will be in engagement with the cone disks 117 on the forward extremities of the shafts 116 and the several chain belts 107, 108, 109 and 113 will all be moving toward the rear end of the carriage, as indi- 3. As soon as the carriage begins to rise positively through engagement with the switch tongues 91, as heretofore explained, the shaft 104 will be moved rearwardly in the slots 123 of the heads 1 14, and the cone friction disks 124 will be caused to engage the cone disks 117 on the rear extremities of the shafts 116, and thereby reverse the movement of the chain belts 107, 108, 109 and 113, and feed the plate forward to and over the chain bolts 77 of the return rack or frame. This return movement of the chain belts 107, 108, 109 and 113 will not be effected until the carriage is fully raised, as shown by Fig. 4, and when the late operated upon by the rolls 2 and 3 has lieen finished and is delivered to the carriage 60, the latter remains in elevated osition and the movement of the chain be ts 107 108, 109 and 113 will be caused to feed the said plate to the rear over the said carriage by shifting the sleeve 10 on-the shaft 7 to bring the friction disk 15 of the shaft 16 into engagement with the friction disk 11 of said sleeve. The finished plate will be received from the rear end of the carriage by any suitable mcans, and after it is fully liberated the sleeve 1.0 will be again shifted to cause the parts to resume the positions shown by Fig. 1 when the same operation may be carried on as just explained. It will be seen thatthe carriage 60, by its lowering and horizontal movements, will be caused to pass under the plate fed rearwardly by the rolls 2 and 3, and said rearwardly fed plate may have considerable projection from the rolls without any interference with respect to the movement of the carriage and with a reliable or certain disposition of the carriage to come into operative relation to the fed plate.
